flow of wetting phase in the pore network, we should decide which corners of
neighboring pore bodies are connected by the pore throats. In the case of corner
pore throat, as shown in Figure B.1a, this is straightforward as it connects the
corners of pore bodies. In the case of edge or face pore throats, shown in figures
B.1b and B.1c, respectively, we assume that they connect corners of neighboring
pore bodies to each other. The question is which corners do they connect. We
have done this though a random processes. For example, in Figure B.2, face
pore throat number 1 connects the faces of pore bodies A and B. Through a
random process, we assign the A-end of pore throat 1 to be connected to one
of the corners a, b, c, or d. the same will be done for the B-end of the pore
throat 1. As a result, pore throat number 1 will be assumed to be connecting
one corner of pore body A to one corner of pore body B. A similar process is
applied to pore throat number 2 in Figure B.2, which is an edge pore throat;
one end will be assigned to corner b or d, and the other end will be assigned to
corner f or e. At the end of this process, all pore throats are assigned to the
corners of pore bodies.
Figure B.2: An example of connections of pore throats (designated
by numbers) to pore bodies (designated by capital letters). Pore
body corners are shown using small letters. To keep the Figure less
crowded, only three pore throats are shown.
